Deep Dive Into the State Design Pattern in Python

In this video, I'll dive into the State Design Pattern in Python, a game-changer for managing state changes in object-oriented programming.

What's new in Django 5.0!

Have you been counting down the days? Not to Christmas... to the new Django release! Django 5.0 is out! Let's unwrap the new features of our favourite Python web framework together.

Using Polars in a Pandas world

Accelerating Generative AI with PyTorch II: GPT, Fast
This post is the second part of a multi-series blog focused on how to accelerate generative AI models with pure, native PyTorch. We are excited to share a breadth of newly released PyTorch performance features alongside practical examples to see how far we can push PyTorch native performance. In part one, we showed how to accelerate Segment Anything over 8x using only pure, native PyTorch. In this post we’ll focus on LLM optimization.

MLOps Course – Build Machine Learning Production Grade Projects

MLOps, short for Machine Learning Operations, refers to the practice of applying DevOps principles to machine learning. This MLOps course will guide you through an end-to-end MLOps project, covering everything from data ingestion to deployment, using state-of-the-art tools like ZenML, MLflow, and various MLOps libraries.

Python Linting in Visual Studio Code – Hinting and Linting Video Series
One of the most important parts of writing code is making sure your code is readable. There are so many positive downstream effects of clean code from its ease to maintain and add features, debug subtle programming errors or find uninitialized variables. Some people call this code hygiene. VS Code has linter extension support that enables you develop faster, produce cleaner code and is tweaked to your set up.
